Courtesy drive to combat road rage

Drivers are being encouraged to post polite messages on roadside signs to combat what motoring groups say is a rise in road rage incidents across New South Wales.

The NRMA is erecting nine electronic boards across New South Wales and the ACT for drivers to post what the organisation is calling "courtesy messages".

Motorists will be able to submit messages via social media or at a series of public meetings.

"We want to put positive messages on these signs that are encouraging people to drive a bit more courteously," NRMA president Wendy Machin said.

"We're asking the driving public to be part of that, to tell us what they think might make us a little bit happier and a little bit nicer on the roads, and we'll put some of those ideas up on these big signs."
